Abstract:
(EN) A communication method and a communication device. In the solution, a sub-frame for transmitting a multicast channel comprises a symbol for downlink transmission, a GP, and a symbol for uplink transmission. The sub-frame for transmitting the multicast channel not only comprises the existing symbol for downlink transmission, but also comprises the symbol for uplink transmission. The uplink transmission comprises HARQ-ACK transmission. In this way, a sub-frame for transmitting a multicast channel can feed back an HARQ-ACK without waiting for an uplink sub-frame, so that the HARQ RTT is reduced.
(FR) L'invention concerne un procédé et un dispositif de communication. Dans la solution, une sous-trame servant à la transmission d'un canal de multidiffusion comprend un symbole pour la transmission en liaison descendante, un GP, et un symbole pour la transmission en liaison montante. La sous-trame servant à la transmission du canal de multidiffusion comprend non seulement le symbole existant pour la transmission en liaison descendante, mais comprend également le symbole pour la transmission en liaison montante. La transmission en liaison montante comprend une transmission de HARQ-ACK. Ainsi, une sous-trame servant à la transmission d'un canal de multidiffusion peut renvoyer un HARQ-ACK sans attendre une sous-trame de liaison montante, de sorte que la durée totale du cycle HARQ est réduite.
(ZH) 一种通信方法及通信设备,在该方案中,传输多播信道的子帧中包括用于下行传输的符号、GP和用于上行传输的符号,传输多播信道的子帧中不仅包括了现有的用于下行传输的符号,还包括了用于上行传输的符号,上行传输包括HARQ-ACK传输,这样,使得在传输多播信道的子帧也能反馈HARQ-ACK,无须等到上行子帧,从而降低了HARQ RTT。
